Improper Operation - WEG CFW-11 Applications Manual

Parameters Description
Description:
These parameters limit the motor current component that produces positive (P0169) or the negative (P0170)
torque. The adjustment is expressed as a percentage of the rated motor torque current.
P1028 – Speed Hysteresis for Inverter in Torque Limit Detection
Adjustable 0.0 to 50.0 %
Range:
Proprieties:
Access groups via HMI:
Description:
This parameter defines the percentage of the motor synchronous speed that will be the hysteresis used to
detect inverter torque limits during the execution of load hoisting/forward or lowering/reverse commands in the
crane horizontal motion application. In other words, if the motor speed is less than (hoisting/forward) or greater
than (lowering/reverse) the hysteresis value when compared to the speed reference, then the inverter torque
limit condition is detected.
NOTE!
A setting of "0.0 %" disables the fault.
P1029 – Inverter in Torque Limit Fault (F775) Delay Time
Adjustable 0.00 to 650.00 s
Range:
Proprieties:
Access groups via HMI:
Description:
This parameter defines a delay time after the inverter in torque limit condition has been detected, before the fault
"F775: Inverter in Torque Limit", is generated.

3.15 IMPROPER OPERATION

This parameter group allows to the user to adjust the conditions to supervise the use of the crane horizontal
motion verifying whether it is being operated properly.
P1058 – Number of Consecutive Alarms for Improper Operation Fault (F777)
Adjustable
0 to 10
Range:
Proprieties:
Access groups via HMI:
Description:
This parameter defines the number of consecutive alarms during the period programmed in P1059 to generate
the fault "F777: Improper Operation". The practical result of this fault is not allowing the user to continue the
crane horizontal motion operation in case of consecutive alarm messages.
NOTE!
The alarms A750, A760, A762, A764 and A766 are not computed in the consecutive alarm counter,
because they just indicate an operation status of the crane horizontal motion.
NOTE!
Setting this parameter in 0 disables the fault.
